Rice root growth encompasses a remarkable genetic diversity in terms of growth patterns, architecture, and environmental adaptations. Root/drought research at IRRI has been ongoing since the 1970s, with a long-term focus on root growth at depth and large nodal root diameter as drought resistance traits. After direct selection for yield during the past decade that is now approaching impact at the farm level, we are seeing that root traits are indeed involved in improved yield under drought. Surprisingly, traits other than deep root growth and large diameter nodal roots have been observed. This presentation will summarize the progress we have made in identifying root traits behind major-effect drought-yield QTLs in genotypes developed at IRRI.

  1. please send information regarding root related QTLs in rice, it helps for my thesis work.
